The mini Whanganui Electronics Case from Aquapac is named after the Whanganui River, a major river in the North Island of New Zealand. For that kind of environment, you really need a case that will meet the challenge for keeping your gear safe and dry. This case is designed with Aquapac's Aquaclip - a rustproof, injection-molded plastic seal. Submersible to 15', the Whanganui will hold your iPhone, mini GPS units. Or, if you prefer, store your personals (passport, camera, wallet) inside to keep them safe from dust, moisture and, worst of all, sand. When using the Mini to protect your phone, you can still talk and be heard. Backed by a five-year warranty, this case can prove to be an invaluable asset against the elements when traveling through marginal climates.
